Why Laser Beams Are the Hottest New Tech in Defense

In this episode of Odd Lots, Joe Weisenthal and Tracy Alloway speak with retired US Army Colonel Wayne Sanders, now a senior defense research analyst at Bloomberg Intelligence, about the rise of directed energy weapons. They discuss how lasers, once considered science fiction, have now become a reality capable of shooting down missiles, the physics challenges researchers had to overcome, why hand-held laser guns remain elusive, and what makes a weapon system 'exquisite.' The conversation also explores the economic costs that shape battlefield adoption and the unique supply chain constraints affecting laser weapon development.

Highlights

•
Lasers Are Now Shooting Down Missiles
Directed energy weapons have advanced from Reagan-era science fiction to real-world defense systems capable of intercepting missiles.
•
The Physics That Had to Be Solved
Researchers had to overcome fundamental physics problems, such as generating sufficient power and maintaining beam coherence, to make laser weapons effective.
•
What Makes a Weapon System 'Exquisite'
Sanders introduces the Pentagon term 'exquisite' to describe weapon systems that are highly effective but extremely expensive and complex.
•
The Economic Calculus of Laser Warfare
The decision to deploy lasers often comes down to cost per shot compared to traditional interceptors like missiles.
•
Why We Still Don't Have Laser Guns
Hand-held laser weapons remain infeasible despite advances, due to power and cooling requirements.
•
The Hidden Supply Chain for Lasers
Laser weapon development depends on specialized materials and components that have limited global supply chains.
